If you find that the price of the currency is already high, but a large amount of funds suddenly intervene, you need to be vigilant. High prices mean higher costs, and unified capital intervention may indicate the existence of dog dealers. Dog dealers invest a lot of money to push up the price of the currency, which is likely to attract retail investors to follow suit and buy, so that they can take over at high prices, while dog dealers withdraw after retail investors buy, leaving retail investors facing potential losses.

Therefore, when the market rises at a high level with shrinking volume, you should be cautious and avoid blindly following the trend. Instead, you should deeply analyze market dynamics and fundamental information to make rational investment decisions.
